Serial No. 495,626.

This invention relates to new and useful improvements in marginal gauges for type setting machines.

It is one of the principal ob ects of my invention to provide means attachable to the frame of a typesetting machine, to signal the operator when the type fed into a partlcular row approaches and reaches the marginal spacing line previously determined for all the rows of the composition set up.

It is another object of my invention to provide means for giving the operator a warning signal that the predetermined marginal spacing is being approached, and the second or final signal to the operator that the word being set up must end the line or be hyphenated to avoid extending the row of type beyond the marginal line allowed. The movement of the type itself, irrespectlve of its shape or dimensions, controls the signal through its engagement with the contacts carried by the gauge arm.

Other important and incidental objects of my invention will be brought out in the anneXed specification and subjoined claims.

In the accompanying drawing Figure 1 is aperspective view of a typesetting machine showing my marginal device attached to the frame thereof. Figure 2 is a sectional view taken through the frame of the typesetting machine shown at Figure 1 and showing my marginal guide in side elevation. Figure 3 is an end view thereof. Figure 4 is a perspective View of the bracket support for my marginal gauge. Figure 5 is a top plan view of the bracket support for my marginal gauge. And Figure 6 is the circuit diagram employed in my invention.

Referring to the accompanying drawing for a detailed description of my invention, the numeral 1 refers to a typesettin machine having a bed plate 2 supported by the frame 3 of the machine. (See Figure 1.)

Slidably mounted on the bed plate 2 is a type receiving chase plate 1 such as is employed in multigraphing machines and the like.

Adjacent the bed plate 2 and attached to the frame 3 is a keyboard 5 similar to a typewriter keyboard and employed to control the type release and ejector mechanism 6 to feed the type into the chase plate 4. I

Mounted on the side of the bed plate 2 at its center and in alinement with the type receiving slot before the ejector 6 is a bracket 7 that is insulated from the bed plate by a dielectric washer 8 such as bakelite. The bracket 7 is secured to the plate 2 by screws 9 and 10 that are received by dielectric bushings 11 and 12 that may likewise be of bakelite. Each bushing is provided with a shoulder 13 that is received by a counterbore 14 of holes 15 and 16 in the bracket to thus firmly and securely attach the bracket to the bed plate without electrical contact. (See Fig ure 2.)

The bracket 7 at its upper end is provided with a vertical flange 17 on one face and a milled recess 18 on the opposite face. Attached in the recess 18 by dowel pins 19 is an inverted L-shaped flange member 20 whose inwardly projecting upper end 21 is provided with a tapered hole 22 to receive from its outer face a steel ball 23 that projects slightly from the inner face of the hole 22.

The ball 23 is retained in the hole by a fiat spring 24 attached to the outer face of the flange 20 by a screw 25 through its lower end. The thickness of the flange 20 is such that the pressure of the spring will at all times force the ball inwardly.

The upper ends of the flanges 17 and 20 are provided with holes 26 and 27 that are in alinement to receive a fulcrum pin 28 for a gauge block 29 that is received between the flanges 17 and 20.

I The block 29 is of rectangular shape and at its fulcruined end 30 is provided with a de pending boss 31 to receive the pin 28. (See Figures 8, at and 5.)

Adjacent the pin 28 the block 29 is provided with a vertical hole 32 at the end of a saw slot 33 extending longitudinally through the block to the end opposite the pin 28.

The top surface of the block is provided with a channel recess 34 co-extensive thereof to receive between the bottom of the recess and a cover plate 35 the gauge arm 36. The cover plate 35 is secured to the block by dowel Jins 37-38 at its fulcrum end and b means proper elevation.

secured to the gauge arm by rivets 4l41 extending through its downwardly sloping cam face 42 positioned so that the face of the approaching type will move under that face and contact the face of the rivets 41 -41.

Then, on further movement, the type will pass beyond the rivets and through cam actlon will raise the rivet faces out of contact with the face of the type. Adjacent the contact block is another contact block 43 also of dielectric material and secured to the gauge arm by rivets 44--44 whose faces are flush with the downwardly inclined cam face 45 of I the block 43. Now as the type passes beyond the first contact block the type face will contact the face of the rivets 4444. (See Figure 2.) 1 V s I An electric circuit comprising an annunciator or signal light 46 on the keyboard 5 and an electric battery 47 (not shown) has one side of the circuit grounded to the frame 3 and its other side connected to the bracket 7 by a terminal screw 48 on the lower face thereof for the conductor 49. (See Figure 6.)

As the type moves into position under the block 40, it will first contact the rivet faces 4 1-41 and thus complete the circuit from the frame 2 through the gauge arm '36, bracket 7 and conductor 49 to warn the operator that the marginal space is being approached and the word being written should complete the line or the word should be hyphenated.

As the operator continues the composition the extreme lower end of the block 40 will raise the rivet faces out of contact with the type to discontinue the signal.

When the extreme length of the line is reached, then the type will contact the rivets 44-44 in the block 43 to again signal tothe operator that the line limit has been reached.

The marginal width is adjustable through the movement of the gauge arm in the gauge block 29 and the top face of the arm is provided with graduationmarks 5O such-as inches and fractions thereof that register with a gauge mark 51 cut into the top face of .the gauge block 29.

The side of the gauge 29 adjacent the flange :20 is provided with a conical seat 52 to receive, when lowered into the working position, the ball 23 to hold the gauge arm at the Having described my invention, I claim: 1. In a typesetting machine, a chase, and

dual means engaged by a type during its forward movement in the chase to apprise the operator, first that a predetermined marginal spacing is being approached and second, that the word being set up must end the line or be hyphenated.

2. In a typesetting machine, a chase, an

adjustable arm pivoted to the frame of the machine and projecting over the chase, an electric signal circuit including said arm, and a contact carried by the latter for engagement by a type moving into said chase, forthe purpose specified. v V

3. In a typesetting machine, a chase, a gauge arm pivoted to the frame of the machine and projecting over the chase, an electric signal circuit including said arm, and two contacts carried, one behind'the other, by the outer end of said arm, for engagement by a type moving into the chase, for the purpose specified. 1

4. In a typesettingmachine, a chase, a gauge arm pivoted to the frame of the machine and projecting over the chase, an electric signal circuit including said arm, a block of insulating material having a lower cam face, and exposed contact rivets securing said block to the outer end of said arm, said rivets adapted to be engaged by a type moving into the chase, for the purpose specified, after which they are cammed above the type.

5. In a typesettingmachine, a chase, a gauge arm pivoted to the frame of the machine and projecting over the chase, an electric signal circuit including said arm, a pair of blocks of insulating material having lower cam faces and exposed rivets securing the blocks, one behind the other, to the under surface of the front end of said arm, for

alternate engagement by a type moving into the chase, for the purpose specified.

6. In a typesetting machine, a chase, a bracket block secured to the frame of the machine, said block formed with a recess in its top portion, a gauge arm pivoted in the recessed portion of said arm and projecting over the chase, a flange on said bracket formed with a depression, a spring pressed ball in said depression adapted to be engaged and forced inwardly by the gauge arm in which there is a depression to receive said ball to hold the arm in a horizontal position over the chase, an electric signal circuit including said bracket block, and a contact carried by the outer end'of said arm for engagement by an inwardly moving type in the chase for the purpose specified.

In testimony whereof I-have hereunto set my hand this 8th day of November, 1930.
